OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 223,398, dated January 6, 1880.

' Application filed November 2G, 1879. l

To all whom it may concern Be it known that I, DAVID SHIELDs, of Sing Sing, in the county of Westchester and State of New York, have invented a new and valuable Improvement in Oil-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had tothe annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawingsis a representation of vertical cross-section of my improved oilstove. Fig. 2 is a detail of the same, and Fig. 3 is a detail showing section of my wicktube.

This invention has relation to oil-stoves; and it consists in the construction and novel arrangement ofthe spring-supports under the main bed-plate, the gauze-covered vapor-Hue from the reservoir and the vapor-chamber and lues surrounding the burner-slots, the perforated air or draft equalizer and its raised supporting-plate, the raised burner-plate and its connected drum and chimneys, and the detachable hinge-connection of said burner-plate and bed-plate, all as" hereinafter shown and described.- 1

In the accompanying drawings, the letter A designates the bed-plate of this stove, supported by legs a, and having attached to the legs the supporting-springs b. Through the bed-plate are made certain apertures c and semiciroular or elongated hinge-holes d, and in its central portion are the slots e e', for the wick-tubes and'vaporue of the reservoir. The latter consists of a pan, B, or vessel of dat] form, having a marginal lian ge, a', whereby it is engaged lwith the ends of the supporting-springs b, when pressed upward between the same, its-position being such that its upper surface is somewhat below the under. side of the bed-plate, leaving an air-space, b', between the two.

C represents the central vapor-flue, which extends upward from the reservoir through the central slot, e, and D are the wick-tubes on each side of said vapor-tube, extending through the side slots, e. The vapor-tube is 5o covered with wire-gauze g, and extends also through a central slot, c2, in the burner-plate E, which forms the base of the drum or body portion F of the stove.

Upon the top of the bed-plate rests, by its bentdown corners or legs, an intermediate supporting-plate, G, slotted at ff for the passage of the vapor-tube and \vicktubes, and

provided with studs g', to support the perforated draft guard or equalizer H, also provided with slots h, for the vapor and wicktubes. The wick-tubes I) are shouldered at JL', and below this shoulder are double, as

shown, a perforated partition, lf, serving to divide the main wick-passage from the blind passage lc', in which is permanently located a piece of wicking or `felt, which serves as a feeder to the main or burning wick, keeping it saturated.

The burner-plate E extends over the airequalizer and its support, and rest by its legs Z upon the bed-plate. It is arranged at such a height that there is an air-space, b2, between its under side and the air-equalizer H, and

below the latter an air-space, b3, and below the supporting-plate Gr of said equalizer an airspace, b4. The object of these successive air-spaces is to provide for free access of air to the wick-tubes by horizontal fines or airspaces, and at the' same time to prevent the spread of the heat from the wick-tubes downward in the direction of the reservoir. t

The burner-plate E is provided with slotted burner-convexities m on each side of the central slot, e2,through which the vapor-flue passes, and upon said burnerplate is seated the drum or body F, having near its lower end a diaphragm, l, which is made with lateral slots m', corresponding to the slots of the burner cones or convexities, but of somewhat larger dimensions, as shown. It has no central slot, as the gauze-covered end of the vapor-flue terminates below it. The space, therefore, under this diaphragm I and above the burnerplate E forms a vapor-chamber, receiving the vapor from the reservoir through the vaporflue, and delivering it through the surrounding crevices or apertures a to the burners, where it is consumed.

N represents the chimneys, which extend upward from the diaphragm-plate I, said chim- IOO neys being usually made with front openings, which are closed by means of mica platesand a hinged li ght-door or mica-holder.

S indicates the cap ofthe drum or body, having the sup1 ortingstlids r andniaiginal ange s. It is bolted to the burner-plate by means of through-bolts t, which connect the parts of the body F together.

The chimney-slots s in the cap are. iianged underneath to t the tops of the chimneys N and keep them in position.

T represents an upper draft plate or attachment, which is designed to be seated on the cap S, and is provided with recessed sides or wings W, above which are register-valves or gates w, and below which are flue-pipes P', having at their upper ends, and under the main valves w, smaller register valves or gates w.

V represents a central register-plate, which is made removable and reversible, and has supporting-studs on one side.

By means ofthese registers andiues thedraft may be kept free while different articles are being cooked, or when the pot or pan is removed from the main central heat to a side heat, or in the reverse direction 5 and by means of connections all disagreeable odor from the oil may be passed off through the pipes P.

The feet of the rear legs ofthe burner-plate E, which is also the base-plate of the drum, are made with curved claws z, which, engag ing with the hinge-holes l of the bed-plate, serve to keep these plates in exact relative position,and as hinges to enable the drum to be tipped bacluvard and supported in an inclined position when access is desired to the wicktubes, vapor-tine, or filling-neck v.

Having described this invention, what I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination, with the gauze-covered vapor-line C from the oil-reservoir and the burner-'cones m, of the horizontal vapor-chant ber into which. said vapor-tine projects, and the crevice-passages n, surrounding the burn erslots, substantially as specified.

2. The combination, with the oil-reservoir B aud the bed-plate A, supported upon legs a, of the under supporting-springs, b, engaging the margin of said oil-reservoir, substantially as specified.

3. The combination, in an oil-stove, with the bed-plate A an d the burner-plate E, supported thereon, of the intermediate studded supporting-plate, G, and the perforated air-equalizer H, resting thereon, thereby t'ormin g the horizontal air-spaces b2 b3 b4, substantially as specitied.

4. The combination, with the hinge hole bearings d ofthe bed-plate, of the rear legs of the base-plate ofthe burner-drum, having claws z, engaging with the hinge-holes and adapted to support said drum in an inclined position when tipped backward, substantially as specitied.

5. rIhe oil-stove consisting of the bed-plate A, burner-drum F, oil-reservoir B, air-equalizer H, and intermediate supporting-plate, G, for the latter, all detachable, and separated by horizontal air-spaces b b2 b3 b4, substantially as specified.

6. The combination, with the burner-plate E, having the slotted burner-cones m, ot' the drum F, having the diaphragm I,vslotted at im to correspond with the slots of the burnercones, and forming a horizontal Vapor-chamber, with crevice-passages u around the slots of said burner-cones, whereby the gases are confined below said diaphragm and conducted to the burners, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
